Abstract
Ultra-wideband (UWB) radio systems have attracted a lot of attention during the last few years. These systems are very low transmission power and spread over a bandwidth of several gigahertz. The very low transmission power and the large bandwidth used, enable a UWB system to co-exist with other narrow band systems. Nevertheless, these narrow band systems may cause interference, which may jam the UWB receiver completely. This paper presents a novel narrow band interference suppression technique for UWB radio systems. It consists of selecting the first strongest multipath components and combining them using a RAKE receiver based on the minimum mean square error (MMSE) criterion. Simulation results reveal that this reduced complexity technique can almost completely eliminate the effect of narrow band interference.
